Syntax

CATCACHE=n | hexX | MIN | MAX

n: specifies any integer greater than or equal to 0 in terms of bytes. If n > 0, SAS places up to that number of open-file descriptors in cache memory instead of closing the catalogs.

hexX: specifies the number of open-file descriptors that are kept in cache memory as a hexadecimal number. You must specify the value beginning with a number (0-9), followed by an X. For example, the value 2dx sets the number of catalogs to keep open to 45 catalogs.

MIN: sets the number of open-file descriptors that are kept in cache memory to 0.

MAX: sets the number of open-file descriptors that are kept in cache memory to the largest, signed, 4–byte integer representable in your operating environment.

Tip:The recommended maximum setting for this option is 10.

Use the CATCACHE= system option to tune an application by avoiding the overhead of repeatedly opening and closing the same SAS catalogs.

CAUTION:

When using both the CBUFNO= and CATCACHE= options, if one of the option's value is set higher than zero, the other option must be set to zero.
